2. Compare the absorption spectrum of the blue dye (1d) to the intensity spectra of light
change in intensity of light passing through the blue dye (1a). Comment on the
wavelengths with a large absorption versus wavelengths with a large intensity.
3. Compare the effect on the light intensity passing through both yellow and blue dye
cuvettes (1c) to the effect on the light intensity passing through each individually (1a and
1b).
4. Compare the absorption spectrum of the green dye (1f) to the absorption spectra of the
yellow dye (1d) and the blue dye (1e).
5. In two or three sentences, clearly explain the relationship between the color a solution
appears to be, and the color(s) absorbed by that solution.
6. Mixing yellow and blue paint creates a green paint, but mixing yellow and blue light
creates white light (reviewing your prelab work, notice that yellow can be made from an
equal mix of green and red light, and an equal mix of all three creates white). What does
this suggest about how paint colors work?
